A study was being done at our District to see who takes more units per semester, students at Cypress College or students at Fullerton College. To test this, the researchers randomly selected 60 Fullerton College students and found that the mean number of units they took per semester was 13.1 units with a standard deviation of 2.4 units. They randomly selected a sample of 65 Cypress College students and found that the mean number of units they took per semester was 11.6 units with a standard deviation of 3.7 units. Test the claim that the mean number of units is more for Fullerton College students than Cypress College students at the a=0.05 level of significance.

Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
